NOTE:
Compressor startups are staggered to prevent high electrical circuit
demand.
Once the cases are running, listen for any unusual sounds or events.
Examples include:
Evaporator fan blade interference. Compressors should run
continuously at startup. Use an amperage meter to check the current
to each compressor.
CHECK each fan to ensure it is running. The discharge air output at the
top inside front of the case (honeycomb area) should be relatively even
across the length of the case. VERIFY there are no leaks at connections
for the condenser water.
START UP AND OPERATION
See the merchandiser's Technical Data Sheet for refrigerant settings
and defrost require ments. Bring merchandisers down to the operating
temperatures listed on the data sheet.
Excessive ambient conditions may cause condensation and
therefore sweating of doors. Facility operators should monitor
doors and floor conditions to ensure safety of persons.
